In my opinion the real fix here is to get TI to use the standard message

it gets discarted.
This is for the future, the goal of my patch is helping people to
get existing DSP programs work with mainline.
Not everyone can or want to rebuild theirs DSP programs when moving to a mainline
kernel.
That's an even better argument to adopt the standard structure as soon as
possible. Modifying the mainline kernel to adapt to vendors' quirks doesn't
scale.
Well, I can't speak for TI.
But I have little hope.
RPMSG_NS_2_0 is a compile time option, you can turn that off and rebuild
the firmware to go back to the standard message structure. Our new firmware
doesn't use that anyway (and it was only introduced to support some OpenMA
firmware that had multiple channels. It was left on by default in some old
firmware SDKs which is why NS_2.0 is in more firmware than it really needed
to have been). Is there some specific firmware you a working with that cannot
be rebuilt?
